assIGNo'R fro M s WATCH-'BRACELET END' nook. n

Application filed August 18, 1927. Seria1`No'."213,823.

This invention relates to certain new and useful improvements in watch bracelet-end hooks, and the primary object thereof is to provide an improved form of keeper or latch for holding the end hook engaged with the usual bail or bar on the side of the watch.

A further object of the inventionis to provide a keeper or latch in which the latter is held in position by the tensionof the resilient nose of the hook.

Still further the invention aims to provide a keeper which ispositively and effectively held in position and which at the same time can be easily and quickly manipulated to either operative or inoperative position, ymore specifically, to provide a keeper which cams against the nose ofthe hook.

Further and other vobjects will be later set forth and manifested.

In the drawings tion;

Figure Ythe hooks; f l

Figure 3 isa side elevation of one end of Figure 1 and i f l a Figure 4 is a section on line 4-4 of Fig. l. 1 f Y n proceeding in accordance with thepresent invention the hook member is com osed of a top 1 having an extension. at its ront, which latter isv bent to form a hook '2. The hook member is terial and conseque tly the free end ofthe hook 2 isy resilient. further provided with sides 3 which depend from its top. The sides 3- are connected by a cross bar 4, which in conjunction sides 3, provides a ing, one end ofthe bracelet'.y The bracelet 5 may be of any form and forms no part of the present invention.

The keeper or'latch is of generally U- shape and has sides 6 which latter are connected at their rear ends by a cross bar 7, the cross bar engaging on top of the bracelet 5 as shown in Figure 4, thereby affording a movement of the keeper lor latch to operative position dueto the bracelet 5 being fiXedly secured to and in the hol low shank provided by the sides 3 and cross vbar 4 as above noted. The keeper orlatch' engage over the hook member and arepivotedthereto `and Figure/1 is a top plan view of the inven-v 2 is a bottom plan view of one of receiving anen 85 formed of resilient ma.

`The hook member is' with the hollow shank in which is received and yirredly secured, as'by solderpivoted to the sides 3 ofV by means of a pivot pin 8, to which latter the bracelet 5 is connected as. shown. The front free end edges of the sides 6 of the keeper or latch are of cam-shape, and', as shown in Figures 3 and 4, areadapted to wipingly engage the free end or nose of the hook 2 so that the latter exerts upward pressure on the cam 9 thereby vto hold the cross bar 7 engaged with the bracelet. way, it will be seen that thekeeper orlatcli can be easily and quickly operatedv and isY reliably and effectively held in position under tension.

It will further ybe seen that they entire Vdevice is composed of but three parts, which may be easily and quickly produced and assembled, and that a positive friction lock for theV keeper is provided vat each of the:

. sides thereof.
